Airway is the first priority because the gag reflex and full consciousness may not yet have returned.
Before you read
Test yourself first: 3 questions
Question 1 of 3
A client in the post-anesthesia care unit (PACU) has a respiratory rate of 8 breaths/min, shallow effort, and an oxygen saturation of 86% after receiving general anesthesia and opioids. Which is the nurse's priority action?
Answer: A. Airway and breathing are the priority in the PACU. With hypoventilation and hypoxemia, the nurse should first stimulate the patient and support ventilation, including encouraging deep breaths and applying supplemental oxygen, before pursuing reversal agents. Maintaining oxygenation prevents hypoxic injury.
Question 2 of 3
Thirty minutes after general anesthesia, a client suddenly develops a temperature of 104 F, muscle rigidity, tachycardia, and an elevated end-tidal carbon dioxide. The nurse recognizes these as signs of which life-threatening complication?
Answer: A. Malignant hyperthermia is a rare, life-threatening hypermetabolic reaction triggered by certain inhaled anesthetics and succinylcholine. Hallmark signs include rapidly rising end-tidal CO2, muscle rigidity (often masseter), tachycardia, and a late but dramatic rise in temperature. Dantrolene is the antidote.
Question 3 of 3
A client has a tonic-clonic seizure. The priority nursing action is to:
Answer: B. Protect the client: ease them to the floor/side, protect the head, turn to the side (recovery), loosen clothing, and time it. Do NOT restrain or put anything in the mouth.
Keep the streak going with more questions like these, each with a full rationale.
What is anesthesia recovery?
Airway, breathing, and circulation are the top priorities because protective reflexes and consciousness return gradually. Discharge from the PACU follows objective criteria such as the Aldrete score. The first priority on PACU arrival is always a patent airway.
Key points to remember
- Airway is the first priority because the gag reflex and full consciousness may not yet have returned.
- The Aldrete score rates activity, respiration, circulation, consciousness, and oxygen saturation for discharge readiness.
- Common early complications include airway obstruction, hypoventilation, hypotension, hypothermia, and nausea.
- Frequent vital signs and continuous monitoring are required until the patient stabilizes.
- Residual anesthesia can cause shivering, confusion, and delayed emergence.
- Malignant hyperthermia is a rare but deadly anesthetic reaction treated with dantrolene.
Signs & symptoms
- Position side-lying if vomiting
- Watch laryngospasm, stridor
- Shivering, hypothermia common
Nursing priorities
- Ensure a patent airway, assess respiratory rate and oxygen saturation, and give oxygen as ordered.
- Position the patient on the side or with the head turned if not fully awake to prevent aspiration.
- Monitor vital signs frequently and watch for hypotension, hemorrhage, and hypothermia.
- Assess level of consciousness, pain, and surgical site, and keep the patient warm.
- Apply discharge criteria such as the Aldrete score before transfer to the unit.
Labs & values
Patient teaching
- It is normal to feel groggy, cold, or have a sore throat as the anesthesia wears off.
- Tell the nurse if you feel nauseated, in pain, or short of breath.
- Do not try to get up alone until staff say it is safe, because you may be unsteady.
Red flags: report now
- Stridor, snoring, or absent breath sounds signal airway obstruction and need immediate intervention.
- A rapidly rising temperature, muscle rigidity, and tachycardia suggest malignant hyperthermia; get help and dantrolene.
- Report a sudden drop in blood pressure, rising heart rate, or excessive surgical bleeding.
